Detector Key Fob Tag

The TVD4 Tag is a normal TV4 tag modified to include a Red, Green, and Amber LED. When the TVD4 tag detects an interrogation field produced by the reader, the Red LED will illuminate for detection zone A and the Green LED will illuminate for detection zone B. When a tag is within range of the reader, the Amber LED will illuminate to indicate a tag is being read. Can be used as a diagnostic tool and in system optimisation.


  • Visual indication of A and B detection zones
  • Visual indication of reader transmission range
